Abstract (en)
[origin: EP2899908A1] The present invention enables a base station apparatus to efficiently notify a mobile station apparatus of control information in a wireless communication system in which the base station apparatus and the mobile station apparatus communicate. An EPDCCH consists of one or a plurality of ECCEs, and each of the ECCEs consists of a plurality of EREGs. When the EPDCCH is transmitted using distributed mapping, each resource element in each EREG is associated with one out of two antenna ports in an alternating manner, and the base station apparatus and the mobile station apparatus communicate based on the association.
